Title: Device and method for allocating jobs in a network
Inventor: ZHANG FUBO
IPC: G06F9/50
Filed: 2000-06-30
Abstract: A device and method for allocating jobs to host computers in a network are disclosed. The device and method groups the jobs into groups of jobs according to predetermined grouping criteria. One of the predetermined grouping criteria is whether or not the duration of the job is less than a predetermined duration. Jobs having similar characteristics are grouped together. One of the characteristics is the resources required by the job to be executed. The group of jobs is then matched and sent to one of the host computers. To facilitate matching, a representative job within each group of jobs is selected and matched to a host computer. The entire group of jobs is then sent to the matched host computer together. The jobs can be sent either sequentially, if the jobs require a resource of the matched host computer that cannot be shared, or in parallel, if the jobs can share the resources of the host computer. Once the matched host computer has completed running each job in the group of jobs, the finished group of jobs are returned from the matched host computer as a group, which further decreases scheduling overhead.

Abstract: Ordinary data groups and index information indicating data names and memory locations of broadcasted data are transmitted in multiplex mode from a data broadcasting station, and received by an onboard terminal and/or an information service station through a data distribution part. The onboard terminal detects the information, which it does not hold, by referring to the index information, and presents a list of data names at the onboard display part. The service station separately stores the data groups and the index information provided from the broadcasting station. In response to the download request from the onboard terminal, the service station examines whether the required data is located in SS memory part by referring to the index data, and captures the required data from external memory locations defined in the index information if the required data is not stored. The download data is encrypted with the cipher key provided by the requester and transmitted through a radio wave.
